Abstract:
PURPOSE:To describe the management and outcome of an ocular surface alkali burn in the setting of previous laser in situ keratomileusis (LASIK). METHODS:This is a case report and review of relevant literature. RESULTS:A 25-year-old man with a history of LASIK presented 4 weeks after a sodium hydroxide splash to his left eye with visual acuity of 20/60 and a nonhealing epithelial defect adjacent to sectoral inferior limbal ischemia in the setting of trichiasis from upper eyelid cicatricial entropion. After topical corticosteroids were discontinued following the repair of the entropion, the patient returned 3 days later with worsening vision and severe diffuse lamellar keratitis with the melting of the LASIK flap. After promptly lifting the flap and debriding the interface, inflammation was managed with oral, instead of topical, corticosteroids. Over several weeks, the epithelium healed, and inflammation and interface edema resolved. At 10 years of follow-up, the patient had developed a localized pseudopterygium with mild corneal neovascularization but maintained 20/20 uncorrected visual acuity. CONCLUSIONS:A chemical burn over a LASIK flap poses a challenge for managing corticosteroids, which are required to prevent diffuse lamellar keratitis but can also contribute to keratolysis beyond the first week after an alkali injury. Oral corticosteroid therapy may be beneficial in this situation, with a low threshold to lift the LASIK flap and debride the interface if inflammation occurs.
